ICE-CAN.

Specification of Letters'ratent.

Application filed July 29, 1919. Serial No. 314,088.

the art that receptacles or containers of this character are subjectedtoconsiderable internal pressure during the expansion of the water as itis converted into ice; in the lifting and dumping of the molded block ofice in the-receptacle; and in the general handling, packing andarrangement of; the receptacles .in the main freezin tank.

It has also been found with the. use of priofdevices of this characterthat when the pans'or receptacles areov'erturned to release the block ofice they are impacted'with considerable force under the thrust of theblock o'f'ice, which weighs between one hundred that the seams of thereceptacle are burst and opened during'such operation. Anotherdisadvantage found with prior receptacles or molds of this character isthat the corners are not capable of withstanding the internal ressureand frequently crack or burst. epair ofsuch injuries to the can cannotbe permanently or easily made and the cans are practically worthlesswhen so split. A further disadvantage found inprior molds is that thebottoms, under the heavy strain and the expansion incident to thefreezing of the water, causes thebottoms to bulge downward within thebase flange and form ice blocks with rounded bottoms making the blocksdiflicult to handle asthey will not stand upright, particularlywhen'depesited delivery wagons and the,

like. q

The object of the present'inventio'n is to provide in a simplyconstructed sheet metal mold or receptacle a construction which obviatesal1 of the above disadvantages and which-has additionally the advantage.of quickly freeing the block of ice when the can is overturned and ofreducin the frictionalcontact, between the sides o 'the bl oclr f formlyandthe can during the withdrawal of the block of ice.

Anotherobject of the invention is to provide a construction of moldwhich may be knocked down and conveniently shipped from the factory toice plants and the like, and which may be stored in quantities in arelatively small space, the object also embracing a novel joint betweenthe meetin edges of the sheet metal body of the can and the bottom edgeof the body and the bot- With these and other objectsin view, theinventionconsists in certain novel combinations and arrangements of theparts as will more fully appear as the description pr'oceeds, the novelfeatures thereof being pointed out in the appended claims.

For a vfull understanding of the invention, reference is to be had tothe} following desciipltlion and accompanying drawings, in w 10 Figure 1is a side elevation of a receptacle Patented Aug. 3,1920. I

wallsofthe mold when the block is being extracted The body 10 has itsrounded corbursting or splitting of .the metallic body 10 at thecorners.

The body 10 may be made in one or more sections, two being shown in thepresent instance, and which are so constructed that ,when assembledthe'sections or sheets of the body meet and overlap at the longitudinalsides of the body so that the narrow sides of the body are uninterruptedand continuous; thus eliminating the formation of seams at such narrowsides where impact and pressure are constantly exerted duringhandling-of the molds and the dumping of thesame. As shown in Fig. 6,the seams in the body 10 are each formed of the overlapping ends of theadjacent sheets of metal and which have interposed between them a stripor layer 18 of tar paper, or other suitable substance forming a packingfor effectively and positively sealing the 'joint between theoverlapping ends and for rendering the seam air and moisture tight.

In the present instance the seam is held together by a longitudinal rowof bolts'14;

carryin detachable nuts 15 at outer sides 0 the body 10, the bolts beingarranged in staggered relation throu bout the end of the can and beingdetacha 1e so that the sections of the. can may me sepa-' rated and thecan thus conveniently handled in relatively small space. By virtue ofthe tapering formation of the body .of the can, the sections thereof maybe made to telescope or interfit when the sections are separated onefrom the other, and thus a large number of cans may be knocked down andpacked into the same space which is ordinarily required for the storageof one 1 10 by bolts 1 Each section of the can is thus substantiallyU-shaped and the seams of the as sembled can are located in thelongitudinal sides of thecan so that the seams are protectedfrom impactand do nothave to sustain the weight of the molded block as the can isoverturned or dumped.

The upper edge of the'can may be reinforced by a ring 16 which may be ofany suitable construction and detachablyl secured to the u p'er edgeportion of the body which may be readily' removed for knocking thestructure down; llhe lower end 'of the can is closed by a bottomformedofsheetqmetal which has its marginal. edge portion bentdownwardand rounded upwardly. to form a U-shaped channel flange 19 atthe margin of the bottom 18 with the flange opening ,upwardly as itcomprises a .pair of spaced walls capable of withstanding considerableimpact and weight and which braces the bottom portion of the can body10. Detachable bolts'20 may be used in securing the bottom of the can ormold 10 to the lower edge of the sheet metal body for facilitating theknocking down of the mold. In order to seal the bottom of the body-10, aU-shaped packing strip 21 of tar paper, or other suitable yieldinginsulating vmaterial may be employed. As shown in Figs. 3 and 5, thepacking strip-21 is of U-shape and fitted in the flange 19 about thelower edge of the body 10 and adapted to receive the bolts 20therethrough for maintaining the packing in position and sealing thepackin flange 19. g The bottom' 18 is re nforced agamst bulgingdownwardly by the provision of ribs. or crimps 22 which are formeddiagonally across the bottom and intersect at the intermediate .portionin the thereof: The crimps 22 projectupwardly into the can so astoprovide a substantial brace with the arch of the brace upward againstthe mass'to be supported,the arch being formed by the upstruckU-shape ofthe IlbS.

A can constructed according to this-invention is of substantiallynormalsize and may be handled in the main tank in the usual manner. Whenthecan is dumped over on one of its narrow sides the impact ofthe weight ofthe can with the molded block therein is not thrust directly upon theseam of the body, and thus the seam is protected against this impactwhich usually opens theiseam and destroys the can. Furthermore, thearrangement of the seam intermediate the lon itudinal sides of the canstrengthens said sides and forms a reinforcement for the can to resistinternal what we claimas new and desire to secure;

1. A knock down ice mold comprising a rectangular body portion, which isdivided longitudinally; into twocomplemental U shaped sections, adaptedto be nested in each other, means for detjachablyconnecting the meeting'e'dges-of ithe, sections to form ahollow body for the mold, a bottomplate having marginal portions constructed to receive and interlock withthe edges of the body, and means fordetachably securing the bottomplateto the body of the mold.

2. A knock down ice mold comprising a rectangular body portion which isdivided longitudinally into two complemental' U shaped sections adaptedto be nested in each other, the meeting edges of the sectionsoverlapping each other when the sections are operatlvely assembled,fastening members detachably connecting the overlapping edges of thesections, a bottom plate formed with a marginal channel flange receivingthe lower edges-of the body sections, and means for det'achably securingthe bottom plate to the body sections.

3. A knock down ice mold comprising arectangular body portion which isdivided longitudinally into two complemental U shaped sections adaptedto be nested within each other, the meeting edges of the sectionsoverlapping when the sections are operatively assembled, boltsdetachably connecting the said overlapping edges, a reinforcing bandapplied to the upper end of the sections, a bottom plate formed with amarginal channel flange receiving the lower edges of the body sections,and fastening members :detachably securing the bottom.

plate and top band in position.

In testimony whereof we afiix our signatures.
